Republicans win Obamacare legal challenge, add to insurer concerns

A U.S. judge on Thursday handed a victory to congressional Republicans who challenged President Barack Obama’s signature healthcare law, ruling that his administration overstepped its constitutional powers relating to government spending. U.S. District Judge Rosemary Collyer, based in Washington, ruled that the administration cannot spend billions of dollars in federal funds to provide subsidies under the law known as Obamacare to private insurers without the approval of Congress.
